It's been a while since I was in here...
I'm wondering if it's possible to create a column chart
where the color of each column changes according to data in
a separate source range. For example, graph the numbers in
column A, and determine their color using the values in
column B. There are only 2 or 3 different possible colors.
Perhaps a series for each? Thanks for any suggestions.

Out of practice,
Everett
